Math is one of those things where it is extremely hard to explain why it is an important set of skills to have to a person who does not yet have them. But if you asked people what skills they would most want to keep in this world, keeping their math skills would most likely rank at about the same level as keeping their interpersonal skills. After all, money is counted and dealt with through math, both in the earning phase of taking it in and in the investing phase of making it work for you. Not to mention the fact that in order to conduct a lot of kinds of conversations (and to do any kind of construction work), at least basic math is crucial to know.
If you are even intending to have any money, you need to have solid math skills. While you do not need to be able to divide six digit numbers in your head like a savant would do, being able to add, subtract, multiply and divide is critical to being able to negotiate any sort of a financial transaction. If you can not do math, then money is going to slip by you like the rushing rapids of a flash flood. Poverty will be your only option in a case such as that.
In addition to that, you will not be able to understand a lot of the basic concepts of such simple things as housing without the skills of math. How do you calculate the square footage of a room when you are looking to rent an apartment, for instance? While it might sound like math is for nerds, everybody in the world has to use it at some points in their lives, for a very wide variety of different tasks which most people just never think very much about. Most folks never think about math’s greatness.
